   \class Global global.h
-  \brief The Global class collects application-wide global functions.
+  \brief The Global class provides application-wide global functions.
+
+  The Global functions are grouped as follows:
+  \tableofcontents
+
+  \section1 User Interface
+
+  The statusMessage() function provides short-duration messages to the
+  user. The showInputMethod() function shows the current input method,
+  and hideInputMethod() hides the input method.
+
+  \section1 Document related
+
+  The findDocuments() function creates a set of \link doclnk.html
+  DocLnk\endlink objects in a particular folder.
+
+  \section1 Filesystem related
+
+  Global provides an applicationFileName() function that returns the
+  full path of an application-specific file.
+
+  The execute() function runs an application.
+
+  \section1 Word list related
+
+  A list of words relevant to the current locale is maintained by the
+  system. The list is held in a \link qdawg.html DAWG\endlink
+  (implemented by the QDawg class). This list is used, for example, by
+  the pickboard input method.
+
+  The global QDawg is returned by fixedDawg(); this cannot be updated.
+  An updatable copy of the global QDawg is returned by addedDawg().
+  Applications may have their own word lists stored in \l{QDawg}s
+  which are returned by dawg(). Use addWords() to add words to the
+  updateable copy of the global QDawg or to named application
+  \l{QDawg}s.
+
+  \section1 Quoting
+
+  The shellQuote() function quotes a string suitable for passing to a
+  shell. The stringQuote() function backslash escapes '\' and '"'
+  characters.
+
+  \section1 Hardware
+
+  The writeHWClock() function sets the hardware clock to the system
+  clock's date and time.
